查询词典 regression coefficient

objective:to investigate the expression and significance of rb in the occurrence, development and regression of infantile hemangiomas.methods:the expression of rb was examined in the proliferative stage and catagen of human hemangiomas and normal skin tissues by using immunohistochemical technique.immunohistochemical technique for factorⅷ-related antigen was used to prove that the cells which expressed rb were endothelium.image analysis system was applied to measure the expression level of rb at different stages of hemangiomas and in normal skin tissues.results:the expression of rb was significantly lower in proliferating hemangiomas than that in involuting hemangomas(p.05).conclusion:rb might play an important role in the regression of human hemangioma endothelial cells and anti-angiogenesis.

目的：探讨rb蛋白在血管瘤发生、发展及退化过程中的表达状况及其意义。方法：采用免疫组织化学方法检测人皮肤血管瘤增生期、退化期及正常皮肤组织中rb的表达水平，并结合第ⅷ因子相关抗原的免疫组织化学染色证实表达rb的细胞是血管内皮细胞。利用计算机图像分析技术测量不同时期血管瘤组织和正常皮肤组织rb表达的积分光密度和面积。结果：增生期血管瘤内皮细胞rb表达水平低于退化期，差异有显著性（p.05），退化期血管瘤内皮细胞rb表达水平与正常皮肤组织相比，差异有显著性（p.05）。结论：rb通过抑制血管瘤内皮细胞增殖和血管生成而在血管瘤的退化过程中起重要作用。

In practical work, we can fit the empirical equation of regression according to least square method when we use the old data, and needs to make the Real-time treatment for new acquired data in the light of the equation, namely, we need combine new acquired data with the original data, then infer the new empirical equation of regression.

在实际工作中，当我们用旧数据根据最小二乘法拟合出经验回归方程后，常常获得一些新的数据，需要对新获得的数据进行实时处理，即要把它和原有数据结合在一起算出新的经验回归方程。

In chapter 2, based on the samples of TP7725 high speed WEDM machine from ShangHai wireless apparatus factory and DK7725e high speed WEDM machine from SuZhou SanGuang electromechanical corporation, the virtues and defects of known process databases are given. For the TP7725 machine which has complete database liner regression model and nonlinear regression model are brought out. The two models are compared for goodness of fit and prediction. And the process regularity is analyzed.

第二章以上海无专厂的TP7725型号线切割机床和苏州三光的DK7725e型号线切割机床为例，分析了国内现存的线切割工艺数据库优缺点；对已存在较完善工艺数据库的TP7725机床，应用其已有工艺数据，分别进行了线性和非线性回归建模，并根据试验结果进行了比较和工艺规律分析。

Results Single factor logistic regression showed that the risk factors to myopia were the distance between eyes and book when reading, reading on the bus, hours spend on doing homework every night, exceeding 40 minutes once reading or doing homework, eyestrain and favorite taste. The result of further multiple logistic regression was that distance between eyes and hook when reading, reading on the bus, eyestrain and favorite taste had statistical difference (P.05) to the model.

结果 单因素Logistic回归分析发现，读书时眼睛与书本距离、车上看书、每晚做作业时间、一次看书写作业持续时间超过40min、眼睛酸累和最喜欢咸味是小学生近视发生的危险因素；进一步多因素Logistic回归分析发现，读书时眼睛与书本距离、车上看书、眼睛酸累和最喜欢咸味对模型的作用有统计学意义（P值均＜0.05）。

Based on data of per mu yield of spring-sown soybean and of cli-mate in Hengyang from 1975 to 1981,the tendency yields are estimatedfirst by the method of orthogonal polynomial regression,and then by theFisher's integral regression equation for the out-tendency yields andclimatic factors in this city.

依据1975～1981年衡阳市的气象资料和春大豆亩产量资料，首先用正交多项式回归方法估计了趋势产量，然后用费希尔积分回归模式和逐步回归方法计算出了该市气候因子和离趋势产量间的积分回归公式。

Also, the establishment of logistic regression model proves that the choice of stock delivery valuation methods doesn't vary greatly by political affairs and cost of contract, while the establishment of multiple linear regression model bears out that there is a statistics significan ce between accounting evaluation, accounting profession judgment from listed companies' non-circulating assets value depreciation and reflux and the scale of major business income and the relation of high and low ratio of debt to equity. Yet, there is no statistic significance between the relationship of the publication of interest encouraging plan and company establishment date.

在此基础上，本文抽取了实施新会计准则体系之前2005年我国上市公司样本，通过建立有序分组的线性趋势检验模型研究证实，以0.05为显著水平，我国上市公司存货收发频繁程度与发出存货计价方法简化程度之间，并不显著存在一般认为应有的线性关系，排除了发出存货计价方法选择这一混杂因素的影响；进而，通过建立logistic回归模型证实，发出存货计价方法的选择也并不显著受政治和契约成本的影响；通过建立多元线性回归模型证实，上市公司对非流动资产减值的会计职业判断，与其主营业务收入的规模和负债权益比率的高低之间的关系有统计学意义，与是否公布股权激励计划和公司成立时间之间的关系没有统计学意义。

Formly, HDR casts classification problems and regression problems into a unified regression problem. Clustering is performed in both output space and input space at each internal node, termed "doubly clustered" and discriminants in the input space are automatically derived from the clusters in the input space. A hierarchical probability distribution model is applied to the resulting discriminating subspace at each internal node.

在图像的分类和检索中，以前的层次判别回归方法把分类和回归统一成回归问题，在每个内部节点进行输入和输出空间的双聚类，输入空间的分类子空间可以自动从聚类中获得，再用层次概率分布模型计算判别子空间，这样就构成了输入空间由粗到精的概率分布，可以准确而且快速地实现高维数据的检索。
